Throughout history, man has, by over-use, consistently reduced the productive capacity of dry lands. This degradation of one-third of the land area of the globe is, unfortunately, increasing. In recent years, world interest has turned to the problems of pollution of the environment and the impending food shortage as world population grows explosively. Thus the attention of international and other agricultural bodies has turned to the need for preserving and developing more effectively the agricultural potential of these areas. This book provides a comprehensive review of present knowledge of the agriculture of dry lands, with special emphasis on measures for conserving their natural resources. Management practices are described which aim at optimizing productivity of rainfed and irrigated agriculture without adverse effects on sustainability. Land use in the dry regions, and its evolution throughout history is described and analysed, and the lessons to be learnt from destructive technologies are stressed. In particular, current proposals for an alternative agriculture are discussed and their justification is questioned. This is a generalist work, which specialists can also find interesting, not only in their own discipline but as a concise way of acquainting themselves with the state-of-the-art in associated fields. Increasing specialisation with each discipline using its own vocabulary leads inevitably to communication problems, and the need for multi-disciplinary teams makes inter-discipline communication indispensible.

It is known that dryland farming is not remunerative due to several constraints. Location specific technologies have been evolved for yield stabilization in dryland farming and conservation of fragile ecosystem by sustainable use of soil and water resources. Drought and flood situations are experienced some where in the country inspite of pletifull resources of waters unshine hours but poverty among farmers still exists. This is a point of sereous concern. Agrotechniques are alone the answer for low productivity (0.8 t/ha) of 90% rainfed farming. To feed over one billion gallowping population of country, there is a need to increase the productivity to 1.5 t/ha by 2010 AD. This book deals with seed, soil, watersheds, crop, weed and nutrient management use of weather forecast, measure to save crops under abiotic stresses like drought and flooding, selection of crops and variety, reclamation of degraded land, organic recycling, agro-meterological approaches, water requirement, early harvest on physiological maturity, agro-hydro modelling and suitable medicinal and aromatic crops to make dry farming remunerative for welfare of common farmers. This is the first comprehensive book where large number of agro-techniques are incorporated. Chapters are written by eminent scientists of national repute who have devoted their life time to solve probable problems of dryland. Agro-techniques can well be adopted with ease by farmers through extension agencies to avoid bankrupsy. Book includes all relevant aspects of rainfed farming and is therefore a valuable addition in Dryfarming and meets the expectations of all those interested in rainfed farming in the country and abroad. Long outstanding demand has thus fulfilled with this book. The novel approach of editor has made the readers task quick and minimized their efforts by compiling all agro-techniques together at one place for benefit of farmers.

The world has made remarkable progress in maintaining adequate food supplies during the past quarter century by introducing yield-increasing technologies such as better genetics, crop protection products, and more efficient use of fertilizers and irrigations. Far more people depend on irrigation in the modern world than during the times of ancient Sumeria. The spread of irrigation has been the key factor in increasing global crop yields. But future scarcity present the single biggest threat to future food production. The shift of water from agriculture to the growing cities and industry almost certainly will impact global food production. This means that dryland agriculture will be increasingly important in meeting food requirement for the growing population. Advaces in plant genetics and agronomic conservation technologies, when considered in concert, continue to provide the greatest opportunities to achieve sustainability and profitability in dryland agriculture and will continue to be the focus of the ARS research program. The ARS is please to join the crop Science Society of America and international center for Agriculture Research in Dry Areas (ICARDA) in sponsoring a symposium “Challenges and strategies for Dryland Agriculture” at the Trisocieties Annual Meeting in November 2002 at Indianapolis, IN. This special publication contains an impressive series of paper by international group of experts on dryland agricultural production, conservation, and policy. The principles, philosophies, and technologies presented in this publication have the potential to contribute to improve food security and livelihoods for the people in dryland regions of the world.

Crop production in the drought-prone tropics has been relatively neglected by research and development workers, largely due to its poor potential for commercial exploitation. Despite this, a considerable amount of information is available on this subject, but there have been few attempts to draw it together and to relate it to the needs of subsistence and small farmers, and to the particular set of constraints under which they labour.

Sustainability is extremely important in dryland farming under global climatic change. Technology devised by various agricultural institutions is provided in this book.Variation in environmental factors may influence entire ecological system which may not be ideal for agriculture. Under such global scenario , plant growth is under geopardy. New varieties have to be developed to suit the varied climate or crop strategy in view of crop domain suiting ideal available temperature has to be framed to make dryland farming sustainable .Various agrotechnology needs to be adapted to avoid depletion in productivity. Global climatic change in future may limit the productivity of available varieties. Corporate farming may come to rescue the problem under present scenario. Various agrotechnologies described in this book may help the farmers and planners to overcome the situation in future. Critical problems have been dealt with probable solutions to suit the requirements .Multicropping system , organic farming, , watersheds promotion, reclamation of degraded soils, soil health cards, use of portrals of weather forecast, early harvest on physiological maturity and use of instant remedies timely under unfavourable season shall ease the failure of crop . Long outstanding demand has thus fulfilled with this book.

From the beginning of agriculture until about 1950, increased food production came almost entirely from expanding the cropland base. Since 1950, however, the yield per unit of land area for major crops has increased dramatically. Much of the increase in yields was because of increased inputs of energy. Between 1950 and 1985, the farm tractor fleet quadrupled, world irrigated area tripled, and use of fertilizer increased ninefold. Between 1950 and 1985, the total energy used in world agriculture increased 6. 9 times. Irrigation played a particularly important role in the rapid increase in food production between 1950 and 1985. The world's irrigated land in 1950 totaled 94 million hectares but increased to 140 million by 1960, to 198 million by 1970, and to 271 million hectares in 1985. However, the current rate of expansion has slowed to less than 1 % per year. The world population continues to increase and agricultural production by the year 2000 will have to be 50 to 60% greater than in 1980 to meet demands. This continued demand for food and fiber, coupled with the sharp decline in the growth rate of irrigation development, means that much of the additional agricultural production in future years must come from cultivated land that is not irrigated. Agricultural production will be expanded in the arid and semiarid regions because these regions make up vast areas in developing countries where populations are rapidly rising.
